The Singapore Sling is a cocktail that was developed sometime before 1915 by Ngiam Tong Boon, a bartender working at the Long Bar in Raffles Hotel Singapore. The current Raffles Hotel recipe is a heavily modified version of the original, most likely changed sometime in the 1970s by Ngiam Tong Boon's nephew.
